The Beechcraft King Air family is part of a line of twin-turboprop aircraft produced by the Beech Aircraft Corporation (now Beechcraft Division of Hawker Beechcraft). The King Air line comprises a number of models that have been divided into two families; the Model 90 and 100 series are known as King Airs, while the Model 200 and 300 series were originally marketed as Super King Airs, with "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates).
The King Air was the first aircraft in its class and has been in continuous production since 1964. It has outsold all of its turboprop competitors combined. It now faces competition from jet aircraft such as the Beechcraft Premier I and Cessna Citation Mustang as well as newer single-engine turboprop aircraft, namely the Piper Malibu and Socata TBM.
